Lower False Positives, More Operational Trust

False positives are the main reason many admins do not deploy external blocklists directly in production. A wrongly blocked service creates tickets, interrupts business processes, and destroys trust in the entire feed.

Cybora therefore does not promise that false positives are impossible. Instead, the risk is actively reduced through source review, collateral-damage assessment, aging, cautious handling of shared infrastructure, and a documented review process.

Why collateral damage matters

An IP address can show malicious activity today and be used legitimately tomorrow. A domain can be compromised while still hosting legitimate subservices. A cloud or CDN address can serve thousands of unrelated customers at the same time.

For production firewall policies, the relevant question is therefore not only whether a signal looks malicious. It is also who a block might affect.

Caution with shared infrastructure

The following targets require additional caution:

• large cloud and hosting providers
• CDNs, reverse proxies, and SaaS platforms
• shared mail, VPN, or identity infrastructure
• provider networks with dynamic addressing
• domains with legitimate primary use and compromised subpaths

Cybora handles such cases more conservatively. The higher the collateral-damage risk, the stronger the evidence must be.

Review instead of blind operation

If a block affects legitimate traffic, it must be possible to review it clearly. Logs, timestamps, affected policy, target system, and affected application matter. The operational workflow is documented in False-Positive Review.

This review path is not a side issue. It is part of the trust model of a production firewall feed.
